| Physical Properties: Sodium sulfate, a small white monoclinic crystal or powder, soluble in water. The aqueous solution is neutral and soluble in glycerol, insoluble in ethanol. When exposed to air, it easily absorbs water and becomes hydrated sodium sulfate. It is a homogeneous polycrystalline substance that is easy to crystallize at temperature. When crystallized from a solution, it has an affinity for iron, iron compounds, and various organic compounds; High purity, fine-grained anhydrous sodium sulfate is called yuanming powder. |
